Abstract: A method, apparatus, and computer-readable medium are described that gather information from subnets of a virtual private cloud, compare the information of the subnets to criteria of components of a service, and identify selected subnets that comport with the criteria. The subnets may be associated with different availability zones. The selection of any subnet may affect the subnets available for the next selection. The process may dynamically adjust for previous subnet selections and may be available as a service. Based on a call to the service with criteria of the components, the service may request information regarding the subnets and return an identified list of subnets for the components. The process may accommodate services during development stages and during deployment stages and/or account for primary and secondary subnet assignments. By dynamically adjusting the available subnets, delays in subnet selection and subsequent deployment may be reduced.

Abstract: An example gear pump includes a pump ring gear; a pump shaft; a pump pinion mounted to the pump shaft and disposed within the pump ring gear, such that external teeth of the pump pinion engage with internal teeth of the pump ring gear, wherein the pump shaft is configured to rotate the pump pinion, thereby rotating the pump ring gear engaged therewith to displace fluid from an inlet chamber to an outlet chamber; one or more cross-holes; a bushing disposed about the pump shaft; and a pocket formed about a portion of the bushing, wherein the one or more cross-holes fluidly couple the outlet chamber to the pocket, thereby causing fluid in the pocket to apply a supporting force to the pump shaft.

Abstract: An online system performs replication of database from one system to another. A source database is replicated to a target database by performing an initial bulk copy followed by repeated change data capture. The system performs batching to group events generated by the change data capture events. The system performs a multi-constrained analysis to determine when a batch is ready for sending. The system uses multiple buffers for transmitting events to decouple the receiving and sending of events. The online system may be a multi-tenant system the source and target databases stores data of tenants. The system determines a tenant score to adjust the resources allocated during event transfer. The system splits an event into partial events, to avoid dependency between the partial events so that tasks can be executed independent of each other. Therefore, the system performs replication with reduced synchronization overhead.
